Starting Android app development begins with a well-defined objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
